iio: inkern: fix channel read regression 



A recent "cleanup" broke IIO channel read outs and thereby thermal
mitigation on the Lenovo ThinkPad X13s by returning zero instead of the
expected IIO value type in iio_read_channel_processed_scale():

	thermal thermal_zone12: failed to read out thermal zone (-22)
